SMBuscapable
SMBuscapable describes devices, components, or systems that support the System Management Bus (SMBus) protocol. SMBus is a low‑speed, two‑wire serial bus derived from I2C and used primarily for system management tasks on computer motherboards, servers, and embedded systems. Common targets for SMBus communication include smart batteries, voltage regulators, temperature sensors, fan controllers, and other management devices.
An SMBuscapable device can participate in SMBus transactions that conform to the SMBus specification. The standard
SMBuscapability is distinct from general I2C compatibility. An I2C device that adheres to SMBus timings may
In practice, labeling a component as SMBuscapable helps designers ensure reliable communication with SMBus-enabled controllers, enabling
